Body language is a form of non-verbal communication, which consists of body posture, gestures, facial expressions, and eye movements. Humans send and interpret such signals almost entirely subconsciously. John Borg attests that human communication consists of 93 percent body language and paralinguistic cues, while only 7% of communication consists of words themselves. Body language may provide clues as to the attitude or state of mind of a person. For example, it may indicate aggression, attentiveness, boredom, relaxed state, pleasure, amusement, and intoxication, among many other cues.
